Purchased Nov. 7, 2017 for $250. This is a current model, one bay NAS unit. Detailed info on the unit can be found here: https://www.qnap.com/en/product/ts-131p

QNAP NAS units have many built-in features that can be enabled as needed: DNLA, Airplay, iTunes, TimeMachine, Media, VPN, web, etc. and can be expanded with many apps such as adding a Plex Media Server, Download station for bittorents, VPN server, etc etc. Here is a listing of apps that can be installed: https://www.qnap.com/en/app_center/index.php?qts=4.3.4&type=1&II=257&for_qts4=&hf=

Easily accessible from anywhere via QNAP Cloudlink which gives you a unique URL to access via a web browser, or other methods such as SSH, FTP, etc. You can also install iOS and Android apps to access and manage the NAS unit. Can be expanded via 3 USB 3.0 ports. A print server is built in as well for adding a network printer via USB.

It is in like new condition in the original box. Comes with power adapter, network cable, and hard drive mounting screws for both SSD/2.5" HDD and 3.5" HDD. Does not come with a hard drive.

There is absolutely nothing wrong with it. I discovered that I needed a 2-bay NAS unit. Warranty until November 2019.
